PCI-E AUXILARY POWER CONNECTORS
Some PCIe add-in cards, especially video cards, require more power than the PCIe spec of 75W per slot
can provide. These cards will have a six or eight position Molex type power connector probably located
at the top or rear edge of the card. The power supply in the expansion chassis has at least eight PCIe
auxilary power cables labeled “PCI-E” available for these card types. GPU card users should verify that
all external power connections to their cards have been made.
